The most recent publicly available data concerning locations that add fluoride to public water dates to 2012. Experts estimate that the number of people drinking fluoridated water has risen about 5% since the data was gathered over a decade ago.
194.2 million people in the United States drink fluoridated water, making it the country with the largest population to do so. It is over 100 million more people than in Brazil, which has 27.2 million people who drink fluoridated water. However, these numbers only account for 64% of the total US population and 41% of the total Brazilian population.
Four other countries have populations of more than 10 million people drinking fluoridated water: 20.7 million people in Malaysia, 17.6 million people in Australia, 14.3 million people in Canada, and 11.8 million people in Chile. This accounts for 44% of Canada’s total population and over 60% of the populations of Malaysia, Australia, and Chile.
The country with the fewest people drinking fluoridated water is Guyana. However, those 45 thousand people make up 62% of the country’s total population. This is interesting when compared to Papua New Guinea, which has only 6% of its population drinking fluoridated water. Even with that small percentage, Papua New Guinea has 102 thousand people drinking fluoridated water, more than double the group in Guyana. One other country has 6% of their population drinking fluoridated water, but for South Korea, a much more populous country, the total number of people is 2.8 million.
The three countries with the smallest percentage of total population drinking fluoridated water are Vietnam, Serbia, and Peru. Water with fluoride is consumed by 4% of the population, or 3.5 million people, in Vietnam, 3% of the population, or 300 thousand people, in Serbia, and 2% of the population, or 500 thousand people, in Peru.
Not all countries with high percentages of the total population drinking fluoridated water have similarly large populations. Hong Kong and Singapore both have 100% of their population drinking fluoridated water and have large populations of 7 million and 5.1 million respectively. Brunei has 95% of its population drinking water with fluoride, which constitutes only 275 thousand people.
